I drive a Ren traffic and it has never missed a beat in 2 years of hard abuse and 108000 miles and nothing has ever broke on it except the gear linkage just recently.I think they are a bit too low geared in first and second but once going in 3rd to 6th they r pretty quick vans...as for uncomfortable try doing a long trip in an older merc vito van they r utter shite vans IMO compared to them a traffic is a really comfy motor...
